PyroCAN
Infrared Temperature Sensor with CAN Bus Interface• Temperature range: -20°C to 1000°C• Raw CAN communications• Adjustable emissivity setting formeasuring a variety of materials• Fast 200 ms sample rate with highstability• Stainless steel housing, sealed to IP65
• Ideal for onboard vehicle temperaturemonitoring, and many other applications
shown actual size

The PyroCAN series is a range of generalpurpose
infraredtemperature
sensors(pyrometers) that measure the temperature ofsurfaces without contact.

Power Supply
12 to 24 V DC+ Sensor #1

The temperature is transmitted digitally every
200 ms via a CAN interface. The sensor’s CAN
ID and emissivity setting may be changed via aCAN command.

OtherCAN
devicesSensor #32

The sensor is suitable for measuring a variety of
non-metal surfaces, including painted materials,
rubber, plastics, asphalt, soil, plants, organic
materials, food and pharmaceuticals. Metals canbe measured if they are painted or heavily oxidised.

All PyroCAN sensors have precision silicon
optics, with a well-defined measurement area.
The sensor measures the average temperature
within the measured spot shown above. A larger
spot is measured at longer distances. The sensor
is capable of measuring at longer distances thanshown, with a larger measurement area.
The wide-angle 2:1 optics of model PCAN21
provide a relatively large measurement area.
They are ideal if the target is large, or the sensor
is positioned very close to the measured surface.
The general-purpose 20:1 optics of model PCAN201
provide a small, precise measurement area.
Accessories for laser sighting are available,
either to aid aiming during installation, or forcontinuous indication of the measurement area.

The PyroCAN is easily connected to existing
networks with other CAN devices. It is ideal forvehicle-based applications in automotive testing,motorsport testing, industry and agriculture,among many others.

The L-shaped fixedmounting bracket offersa rigid support for thesensor and allows fineadjustment in a single
plane.

ADJUSTABLE MOUNTING BRACKETS

The adjustable mounting bracket consistsof a fixed mounting
bracket plus another Lshaped bracket. Whenassembled as shown
the adjustable mounting
bracket offers a rigid
support for the sensor
and allows fine adjustment in two planes.

AIR PURGE COLLAR

The air purge collar
is used to keep dust,
fumes, moisture andother contaminants
away from the lens. Air
flows into the fitting on
the side and out of theaperture at the front.

The air/water cooled
housing allows thesensor to withstandambient temperatures
which exceed thenormal 90°C limit. Airor water (depending on
the degree of coolingrequired) flows into one of the fittings on the side andout of the other. To prevent condensation forming on thelens, the air/water cooled housing is supplied completewith an air purge collar. Please note, the air/watercooled housing must be ordered with the sensor andcannot be fitted by the user.

The Laser Sighting
Tool screws onto thefront of the sensor
during installation andindicates precisely
where the sensor
is aiming. Once thesensor has been
aimed at the centreof the target and locked in position the Laser Sighting
Tool can be removed. The laser is activated by meansof a push button on the front of the tool which has alatching mechanism.

DUAL LASER SIGHTING BRACKET

Provides a rigid
mounting for thesensor. Two parallellasers continuously
indicate the centre of
the measured spot,
while measurements
are being taken.
